• Move the orientation handle to its extreme
right position. Now the N/S crystals should be
blue, and E/W yellow (fig. 52).
• Be sure to test crystals with the orientation
handle in each position to insure positive
identification.

The following is the procedure for identifi-
cation of pseudo gout:
The test for pseudo gout is done identically to
the test for gout. However, the color change is
opposite that of Gout. That is, with the handle at
the left extreme, N/S crystals are blue and E/W
crystals are yellow, and vice versa with the level
at the right side (fig. 53).
